bt_hogp_rep_write_wo_rsp can only send one Byte one time

[Martin Evans]

Hi,Nordic team

I am programming with nrf52833,ncs v2.9.0,base on peripheral_hids_keyboards and central_hids.

On central I call bt_hogp_rep_write_wo_rsp can only send one Byte at one time,and mtu is 23(it should be sent 20Bytes at least).

my call is 

uint8_t data = 0x01;

 bt_hogp_rep_write_wo_rsp(hogp, hogp->rep_boot.kbd_out, data, len, write_cb);

//upper is ok,I can catch data in peripheral

uint8_t data[8] = {0x01, 0x02, 0x03,0x04,0x05,0x06,0x07,0x08};

bt_hogp_rep_write_wo_rsp(hogp, hogp->rep_boot.kbd_out, data, len, write_cb);//this is not ok but return 0(success),and cannot catch data in peripheral

Best regard

Hi, 

You're passing the array data directly to the function. Make sure you're passing the correct pointer to your data array. The bt_hogp_rep_write_wo_rsp function signature expects const void *data the parameter, and also checks if the length parameter is correct.
